I have a mate's L322 here (been here for weeks) that I am quickly losing all remaining patience with. He had the AA bring it here, dead.

Checked it over - no fuel pressure. Reading just 1 bar from the fuel pressure sensor (reading the live data with a Snap On Solus Pro).

So I checked there was fuel pressure reaching the filter - and there was.

I changed the filter.

I added another electrical rotor cell fuel pump right before the filter - this brought the fuel pressure up to 3 bar (still nowhere near enough).

I changed the solenoid on the back of the pump.

I changed the entire pump (Autodata claims a 1 hour job. my backside it is.)

I even tried unplugging the fuel pressure sender, and it still shows the same.

There is still no sign of any fuel in the fuel rail.

Any suggestions that don't involve a gallon of petrol and a box of matches?
